tus having rotary cylindrical elements, as in 3 my Patent i\o. GTLBAG, granted May 1 1, 1901,

of the application for which this present case is a division: and to this end it consists, essentially, in the combination, constructirm, and arrangement of packing-rings and peripheral conveying means for rotary cylindrical elements and means for uniting sections of rotary cylindrical elements and for supporting said elements at the points where said sections are united. as hereinafter fully described, and ably composed of cylindrical sections u, Figs.

pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming part of this specification, in which like letters indicate corresponding parts in all the views.

Figure l is an elevation of a portion of my conveying apparatus. Fig. 2 is an enlarged horizontal sectional view taken on line 2 Fig. 1. Fig. 3 is an enlarged sectional view, partly broken away, of a portion of the parts shown in Fig. 2, illustrating the packing-ring and the peripheral feeding means for one of the cvliinirical elements. Fig. A is a sectional view taken on line A A, Fig. 3. Fig. 5 is an enlarged sectional view of a portion of the parts seen in Fig. 2, illustrating the means for uniting the sections of one of the cylindrical elements. Fig. 6 is an elevation of one of the antifriction-bearings for the cylindrical elements. Fig. T is an edge view of a portion of the parts seen in b.

A A, A A, and B are respectively a pinrality of rotary cylindrical elements and a casing constructed and operating in the same manner as the rotaryconveyer elements A A A A and the casings B of my aforesaid patent, No. UTA-3&6. As best seen in Fig. 2, the

rotary elements A A are arranged end to end. i The rotary elements A A are also arranged end to end and substantially parallel with the former rotary elements, and the casing b communicates with the elements A A A A and contains mechanism for transferring the material from one of the rotary elements to another. The opposite side walls of the casing B are provided with openings /1 for receiving the contiguous ends of the rotary elements A A A A and with chambers or stutling-boxes b, which are of less cross-sectional size than the casing 13, project outwardly from said walls, and inclose parts of the rotary elements A A A A. So far as my present invention is concerned, the rotary elements A A A A may be any rotary parts, and consequently l have deemed it unnecessary to describe the means shown in Fig. l'for actuating said elements and the means shown in Fig. 2 for transferring material from one element to another.

The rotary elements A A A A are prefer- 2 and v5, arranged end to end and united and supported by the means best seen in Figs. 5, (S, and 7, which consists of collars a u clamping means 1/, and antifriction members u. The collars 1/ u are arranged side by side,

3 are secured to contiguous ends of the sections a by suitable fastening means, as rivets 11", and are provided with shoulders or flanges a, projecting from the outer ends of their peripheral faces. Said collars 1/" encircle the collars u 1/ and are formed with annular grooves 11 in the outer ends of their inner faces for receiving the shoulders 11'' and with projections 11, arranged between the shoulders 11. The clamping means 1/ consists of bolts, which are disconnected from the collar (1, are passed through the collars u u, and draw the collars u u together, thereby clamping said collars (I in position and securing the sections 1/ together with a substantially air-tight joint. Said antifriction members 1/ are here illustrated as rollers journaled in the opposite ends of rocking frames 1/" and formed with peripheral grooves for receiving the collars (,i I) represent, respectively, the packingrings and peripheral feeding means of my present invention. Said packing-rings O, as best seen in Figs. 2 and 3, are arranged in the outer ends of the chambers or stuffingboxes 1) between internal shoulders 1/ of said chambers or stuffing-boxes and are each composed of arc-shaped sections 0, formed of wood and having their adjacent ends tapered and lapped upon each other. Each of said sections is provided with a bow-shaped spring 0, arranged between contiguous surfaces of the chamber or stuffing-box b and said section for forcing the section independently of the remaining sections of the corresponding packing-ring into close contact with the contiguous part of the cylindrical element encircled by said packing-ring. The peripheral feeding means D consists of helical flanges or conveyer-blades encircling the parts of the elements A A A A, arranged within the stuffing-boxes 6 between the openings Z) and the shoulders 6 Said means D operates to feed from the packing-rings C through the openings b, the material tending to pass outwardly from the casing B through the chambers or stuifing-boxes Z).

The construction and operation of my apparatus will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be apparent that more or less change may be made in the component parts thereof without departing from the spirit of my invention.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a conveying apparatus, the combination with a rotary cylindrical element, and a casing having a portion thereof inclosing said element, of a packing-ring surrounding said element interposed between the same and the inclosing part of said casing. said ring comprising a plurality of arc-shaped sections having overlapping ends, whereby the continuity thereof is maintained in the adjustments of the same, and a spring secured substantially centrally of the periphery of each section, the ends of said springs finding bearings against the contiguous wall of the casing, substantially as described.

2. The combination of a casing for receiving material, said casing being provided with an opening and a rotary cylindrical element having a part thereof passed through the opening, and peripheral means on the cylindrical element for feeding said material from the opening toward the interior of the casing, substantially as and for the purpose set forth.

3. The combination of a casing for receiving material, said casing being provided with a chamber or stufiing-box, and a rotary cylindrical element having a part thereof revoluble within the chamber or stuffing-box, and peripheral means on the cylindrical element and within the chamber or stufiing-box for feeding said material from the chamber or stuffing-box toward the interior of the casing, substantially as described.

4. The combination of a casing provided with an opening, and a rotary cylindrical element having a part thereof passed through the opening and provided with a peripheral spiral conveyer-blade for feeding material away from said opening toward the interior of the casing, substantially as and for the purpose described.

5. The combination of a rotary cylindrical element, a casing having a chamber or stuffing-box for receiving a part of the cylindrical element, and a spiral conveyer-blade on the exterior of the oylind rical element within the chamber or stufiing-box for feeding material from the chamber or stufiing-box to the interior of the casing, substantially as and for the purpose specified.

6. The combination of a rotary cylindrical element, and a casing having a chamber or stufiing-box for receiving a part of the cylindrical element; with a packing-ring Within the chamber or stuffing-box encircling the cylindrical element; and a spiral conveyerblade on the exterior of the cylindrical element within the chamber or stuffing-box for feeding material away from said packing-ring toward the interior of the casing, substantially as and for the purpose set forth.

7 The combination of a rotary element composed of sections arranged end to end and formed hollow for permitting the feeding of material therethrough, a collar encircling the sections, and means cooperating with the sections and the collar for forming substantially air-tight joints between contiguous surfaces of the sections and the collar and thereby preventing the escape of the material, substantially as and for the purpose described.

8. The combination of a rotary element composed of sections arranged end to end and formed hollow for permitting the feeding of material therethrough, with collars arranged side by side and fixed to the ends of the sections, an additional collar having a part thereof interposed between opposing surfaces of the former collars, and means disconnected from the additional collar and connected to the former collars for drawing said former collars together and forming substantially air-tight joints between contiguous surfaces of the collars and thereby clamping the additional collar in position and preventing the escape of the material, substantially as and for the purpose specified.

9. The combination of a rotary cylindrical element composed of cylindrical sections arranged end to end, collars arranged side by side and fixed to the ends of the sections and provided with shoulders projecting from the outer ends of their peripheral faces; of an additional collar encircling the former collars and having the outer ends of its inner face formed with. annular grooves for receiving said shoulders, and disconnected from the additional collar and passed through the former collars, means for drawing the former collars together and thereby clamping the additional collar in position and securing said sections together with a substantially air-tight joint, substantially as and for the purpose the additional collar in position and securing 15 said sections together with a substantially air-tight joint, and antit'riction members for supporting said additional collar, substantiall as and for the purpose speeilied.

In testimony whereof I have hereunto signed 20 myname, in the presence of two attesting" witnesses, at Syracuse. in the county of Onondaga. in the State of New York, this 11th day of May, 1901. V
